Early Life and Rise in Local Politics
Born on June 15, 1940, in J.B. Molina, Santa Fe, Usandizaga pursued a legal education before entering the political arena. He joined the Radical Civic Union (UCR), one of Argentina's oldest and most influential political parties, in 1961. His ascent began at the local level, where he served as a councillor before achieving a historic milestone in the city's administration.
Following the restoration of democracy in Argentina in 1983, Usandizaga was elected as the Mayor of Rosario. He served his first term from December 11, 1983, to December 10, 1987. His leadership during this era was critical in establishing democratic governance at the municipal level.

The 1989 Resignation
Usandizaga was re-elected for a second four-year term; however, his tenure was cut short. Known for his passionate and hot temper, he had publicly vowed to resign if Carlos Menem won the presidency. Following Menem's victory, Usandizaga honored his promise and left office on May 22, 1989. He was succeeded by Héctor Cavallero of the Socialist Party.
National Political Career and Legislative Service
After his time as mayor, Usandizaga shifted his focus toward provincial and national leadership. He campaigned for the Governorship of Santa Fe in 1991, 1995, and 1999. Despite his efforts, he did not win these elections, a result attributed in part to the Ley de Lemas (Law of Mottos), a now-repealed electoral system that influenced how votes were aggregated.
Despite the gubernatorial losses, he found success in the legislative branch. He was elected as a provincial representative (Diputado) in the National Congress in 1993. He later transitioned to the upper house, serving as a member of the Argentine Senate from November 29, 1995, to December 9, 2001. Although re-elected, he announced his retirement from active politics at the end of 2002, officially stepping down during the partial renewal of the Senate on December 9, 2003.
Leadership at Rosario Central
Beyond the halls of government, Usandizaga was a devoted supporter of Rosario Central, the football club he had followed since childhood. In 2007, he transitioned his leadership skills to sports management, winning the club presidency with 63% of the vote.
Usandizaga passed away on January 4, 2026, at the age of 85, due to complications arising from multiple strokes.
